Reddcoin when i was active it was trading at 8 satoshi and people were calling it a dead shitcoin because the value plummeted to 1 satoshi. Didnt knew that it would one of the profitable coins during the bullrun.
I've fooled around with staking rdd in the past, but it hasn't exactly held its value over time. Right now it's trading at around 12 satoshis, which isn't really a great performance. On the other hand it isn't quite dead. The only thing with that particular coin is that it didn't find the use it was intended to, which I *think* was as a tipping mechanism on reddit. Members of that forum can already do that with doge and it works fine.
Dead coins to me are ones trading for 1 satoshi and really aren't trading at all, meaning that there are no buy orders in sight. I've never bought any of those, because it's too risky and I don't have any strong feelings towards any of them. Nobody wants them, nobody's trading them, and there usually aren't any miners even mining them, so you couldn't send them to a wallet even if you wanted to.
Who would get behind any coin like that? I don't think those could be resurrected unless there were a bunch of people interested in doing it. One person wouldn't make much of a difference.
